Calculate the area of the composite figure, which is not drawn to scale.

Answers

First, I would multiply 17cm by 22cm to get 374, which is the area of the rectangle. Then to find the area of the triangle, I would multiple 12cm by 19cm and the divide that by half to get 114. I would then add 374+114 to get 488cm as your answer.

The total area of the composite figure will be equal to 488 square meters.

What is an area?

The space occupied by any two-dimensional figure in a plane is called the area. Here we have two figures a rectangle and a right-angle triangle.

We have the following data:-

Rectangle L = 22 cmRectangle w= 17 cmTriangle B= 19 cmTrinagle H= 22-10= 12 cm

Total area = Area of rectangle  +  Area of triangle

Total area = (L x W) + (1 / 2)[ B x H]

Total area = ( 22 x 17 ) + (1 / 2)[  12 x 19 ]

Total area = ( 374 + 114 ) = 488 sq2uare meters

Therefore the total area of the composite figure will be equal to 488 square meters.

The area of a rectangle is 294.4 sq.cm. The length of one side is 16cm. What is the perimeter?
Area = L x w
Perimeter = L + L + W + W

Answers

the perimeter is 68.8cm

Ok so because this is a rectangle the line directly across (paralell) is equal, so if one line is 16cm, the line parallel to that will also be 16. Then the formula for area is LxW we'd plug in the numbers we know to get 294.4[tex]cm^{2}[/tex] =16 x W

then we divide 16 by both sides to make it even to get 18.4cm=W. Now we just plug everything in to the perimeter by doing 16 x 2 + 18.4 x 2 to get

294.4 / 16 = 18.4 = other side length
2 (18.4) x 2 (16) = 68.8cm perimeter

What is the measure of angle B in degrees?

Answers

Answer:

Step-by-step explanation:

The sum of angles in a triangle is 180

we know that angle C=112=180

<C=180-112=68

<A=180-(68+51)=61

<B=180-61=119

Answer:

Your answer will be 17˚

Step-by-step explanation:

1. You find the measures of the known angles (Which A = 51˚ and C = 112˚).

2. You find the unknown angle.

3. You add up both the measures of the known angles (which are A and C).

4. Take the sum of the two known angle measures and subtract that from 180.

5. You end up with the now known measure of angle B, which is 17˚.

Keith bought 14 gallons of paint to do up the classrooms in his daycare center. How many classrooms can be painted in all, if each room requires 1 3/4 gallons of paint

Answers

I think the answer is 8 I’m not sure

8  classrooms can be painted in all, if each room requires  [tex]1\frac{3}{4}[/tex] gallons of paint

What is Division?

A division is a process of splitting a specific amount into equal parts.

Given that Keith bought 14 gallons of paint to do up the classrooms in his daycare center.

Each class room requires [tex]1\frac{3}{4}[/tex] gallons of paint.

We need to find how many classrooms can be painted by 14 gallons of paint.

To find this we have to use the division.

We need to divide 14 by  [tex]1\frac{3}{4}[/tex] gallons of paint.

[tex]1\frac{3}{4}[/tex] is converted to improper fraction

[tex]1\frac{3}{4}[/tex]=7/4

Now divide 14 by 7/4

14/7/4=14×4/7=8

Hence, 8  classrooms can be painted in all, if each room requires  [tex]1\frac{3}{4}[/tex] gallons of pain
